Unless you bought your device the day it came out on the market, the manufacturer has probably already issued a few updates and patches for it. These are designed to improve the device’s function and, importantly, to plug any security holes the device may have. They’re free and you’re entitled to them, so why wouldn’t you get them?
Want to know who buys devices the day they come out? Hackers. They’re looking for those security holes so they can exploit them before the company has time to fix them. Even after the holes are plugged, they can still exploit them on any device that hasn’t yet been updated. That means your device, if you’re playing games on it and ignoring updates.
Bottom line: Right out of the box — as soon as you get your hands on it — install all available updates for your new device. Then make sure you keep up with all future updates and install them as soon as they become available.
